Question

Orthocentre of the $	riangle A B C$, where $A \equiv\left(a \cos 	heta_1, \mathrm{a} \sin 	heta_1ight), B \equiv\left(a \cos 	heta_2, a \sin 	heta_2ight)$ and $C \equiv\left(a \cos 	heta_3, a \sin 	heta_3ight)$ is

Accepted Answer

$\left(\mathrm{a} \Sigma \cos 	heta_1, \mathrm{a} \Sigma \sin 	heta_1ight)$

Answer

$\left(\frac{2 \mathrm{a}}{3} \Sigma \cos 	heta_1, \frac{2 \mathrm{a}}{3} \Sigma \sin 	heta_1ight)$

Answer

$\left(\frac{\mathrm{a}}{2} \Sigma \cos 	heta_{1,} \frac{\mathrm{a}}{2} \Sigma \sin 	heta_1ight)$

Answer

$\left(\frac{3 \mathrm{a}}{2} \Sigma \cos 	heta_1, \frac{3 \mathrm{a}}{2} \Sigma \sin 	heta_1ight)$
